Encapsulated dry-type transformer

The encapsulated dry-type transformer for underground networks can transform the HVA voltage level of the low voltage distribution network.

Main characteristics

The encapsulated dry-type transformer for underground networks can transform the HVA voltage level of the low voltage (MV/LV) distribution network.

• Transformer for interior installation
• AN cooling mode
• Copper and aluminium coils, depending on the power
• Crystal-oriented iron-silicon sheet magnetic circuit
• Power: from 160 kVA to 2500 kVA
• Frequency: 50 Hz
• Primary rated voltage: from 5 to 35 kV with adjustment +/- 2.5% +/- 5% by switching bar that can be moved when switched off (option for dual voltage device, contact us).
• Secondary rated voltage: 410 V (other voltage, contact us)
• Dry transformers comprise coils enclosed in an epoxy resin to ensure their good resistance to thermal shocks and to prevent cracking of the resin over time, a tolerance to the ambient environment and a good fire resistance.
